| 英文摘要: |
| In this paper, the dimensionless form of convection-dispersion equation in miscible displacements is deduced.The higher-order scheme is implemented to solve the model, and several samples are given, in which, the comparison between the experimental results and the numerical results of this paper validates the reliability and accuracy of the numerical model. Good results are acquired. This numerical model can be applied in many fields such as pollutant transport in soil or groundwater, and air pollution. It also can be used to study the problem of mass transfer. |
